Abstract: A seat back for use in private or commercial vehicles is disclosed constituting a pulsation cushion formed having a plurality of expandable chambers interconnected by pressure limiting valves. The valves are responsive to fluid under pressure to produce a sequential rolling wave in the chambers to modify the cross-sectional amplitude of the seat back in the longitudinal and/or transverse direction thereby to massage the back of a person occupying the seat. An adjustable pulsing device is provided to control the supply rate of the fluid and the frequency and amplitude of pulsation.
